Precautions

This medication should not be taken by infants under 5 years old.

People with hypertension, heart, or kidney diseases must consult a specialist before taking this medication. Consultation is also required before use for those with swelling, body weakness, or weak stomach. Individuals with a history of allergic reactions such as rash, redness, or itching due to medication should exercise caution. Those taking other medications, pregnant or possibly pregnant women, and seniors must consult a specialist before use. The medication contains colorant Yellow No. 5, so those allergic to this component should use it carefully. If symptoms such as decreased urine output, swelling of the face or extremities, drooping eyelids, elevated blood pressure, or headache occur during use, immediately stop taking it and consult a specialist. If unusual symptoms such as muscle weakness, limb cramps, or paralysis occur, discontinue use and consult with medical personnel. If symptoms such as skin rash, itching, loss of appetite, gastric discomfort, or nausea appear, stop taking the medication immediately. It is important to consult a specialist if symptoms do not improve even after taking this medication. The prescribed dosage and frequency must be strictly followed, and long-term use requires consulting a specialist. When administering to children, thorough guidance and supervision by a guardian are necessary. Caution is advised when taken together with potassium-containing medications or those containing licorice, as well as certain diuretics, due to the risk of muscle weakness or hypokalemia. Care must be taken to ensure that there is no overlap in components when taking this medication with other herbal medicines. This medication should be stored in a cool, dry place away from direct sunlight, and must be tightly sealed after use. It is also essential to keep it in a safe place out of reach of children.
